Since the Citrix Web Interface login URL could not be parsed, the settings must be configured manually.  Choose 'View Source' in the browser to view the HTML source of the login page.  Submit URL can be determined from the 'action' attribute of the 'form' tag.  Username and password variables will be the 'name' attributes of the appropriate 'input' tags.
